SOFTWARE RESET

This reset method must only be used once the AD4080 is in an idle

state, where conversions are not being clocked, and any existing

conversion is completed.

A software reset is achieved by issuing the following two writes to

the Interface Configuration A register (see the Interface Configura-

tion A Register section, Address 0x00):

1. Set SW_RESET and SW_RESETX bits to 1 by writing 0x81 to

the register.

2. Then, issue another write command that sets either or both of

those bits to 0.

This action returns any previously configured registers to their

default settings, except for the ADDR_ASCENSION bit from the

Interface Configuration A register, which keeps its previous value.

The contents of the FIFO, if any, are also not affected by the

software reset. The ADDR_ASCENSION bit and FIFO data only

return to their default settings after a hardware reset or a full

power-up happens.
